Simulation And Software Development Of Hydraulic Fracturing In Reservoir Of Kuqa Mountain

The oil and gas geological conditions of Kuqa mountain reservoir are mainly manifested as low porosity,low permeability and natural fracture development,and the conventional development is difficult.Horizontal well technology with large-scale hydraulic fracturing technology is an important means to develop the block efficiently.In the process of reservoir reconstruction,the production mechanism of this kind of reservoir is mainly through the natural fractures and porosity developed by the hydraulic fracturing reservoir to improve the oil and gas transportation capacity of the near-well area and improve the single well production.Therefore,it is important to study the path expansion and the law of the construction of hydraulic fractures in the reservoir.In this paper,a simulation study on the hydraulic fracturing expansion of the Kuqa reservoir is carried out.The simulation software of the hydraulic excavation of the Kuqa mountain reservoir is developed,which can provide reference for optimizing the design of hydraulic fracturing.The main research work is as follows:(1)In view of the characteristics of Kuqa fractured reservoirs,based on the large-size real triaxial hydraulic fracturing physical simulation experiment equipment,the interaction between hydraulic fractures and natural fractures is carried out,and the characteristics of hydraulic fractures are studied;(2)Aiming at the characteristics of hydraulic fracturing design of Kuqa fractured strata,the design process of hydraulic fracturing design based on geomechanics is designed,and the fracturing construction parameter optimization module is designed.(3)Researching and development of three-dimensional modeling module to achieve the natural cracks,geological stratification,in-site stress and other geological parameters and wellbore,perforation and other construction parameters of the three-dimensional can be displayed;(4)To optimize the hydraulic fracturing crack simulation program code design,decoupling the calculation module and optimize the module interface to achieve the program easy to update and maintain the characteristics.
